I suspect the guy paid (or otherwise induced) someone to punch him in the head. It's a total fascist right meme to make out like the left is all about physical violence and the right is all cream puffs except for officially sanctioned violence.

Well, he did induce him by being a Nazi, but I'm not seeing where you think it's fake. I don't know for sure, but that guy is dressed pretty Black Bloc. He's probably an anarchist.

And who is going to be swayed by actual fascists memes claiming that it's somehow "liberals" who are violent, and not them, the ones whose entire raison d'etre is genocide?

I get a little tired of the constant focus on fucking "optics," like being polite and civil is somehow magically going to make people be reasonable. Because it's pretty obviously not true. If you didn't know that already, we recently saw that demonstrated.
